Effect of ART techniques on growth of offspring. Body weight and Z-score analysis in male (A and B) and female (C and D) offspring. Multilevel random effects regression analysis. *Indicates a significant difference (P < 0.05) between NM and other treatments; ⧮ denotes NM vs. (IV-ET-2Cell, IVF-ET-2Cell and IVF-ET-BL) at Week 3 and NM vs. IV-ET-BL at Week 4 (P ≤ 0.05), Δ indicates IV-ET-2-Cell vs. IV-ET-BL and ○ indicates IVF-ET-BL vs. IVF-ET-2Cell (P ≤ 0.05). Mean (±SEM) body weight from 3 to 27 weeks (from 8 to 13 litters); n of mothers or foster mothers ♀, n of offspring.
